SPINDLE=SHAP1NG DEVICE,

SPECIFICATION forming part of Letters Patent No. 740,296, dated September 29, 1903 Application filed May 22,1902. Serial li o. 108,451. (No model) -To all whom it may concern:

Be it known that I, ARTHUR C. MoFFI'rT, residing at Sheboygan, in the countyof Sheboygan and State of ,Wisconsin, new and useful Improvement in Spindle- Shaping Devices, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification. g

This invention has vrelation to improvements in machines or devices for shaping, turning, or forming spindles or spindle-like articles from wood or similar material.

The object of the invention is to produce a device by means of which blanks of wood fed thereinto and held against rotation may be turned or shaped as desired.

A further object of this invention is to produce a device employing tools rotatable about the work for automatically turning or shaping spindles or spindle-like articles from wood or similar material of a predetermined contour or after a certain mold or form.

These and other objects I attain in a device constructed as described in the specification and illustrated in the accompanying drawings, in which- Figure 1 is a View with portions in section and portions broken away of a device embodying this invention. Fig. 2 is a front elevation of said device. Fig. 3 is a cross-sectional view of the device looking toward the front thereof and taken on line 3 3 in Fig. 1. Fig. at is a detail sectional view of a portion of the device looking toward the top thereof and taken on line a at in Fig. 3.

Throughout the several views like elements are denoted by similar characters.

The device consists of a standard 5, mounted upon a base 6 and bored at its upper end to form a hearing or journal 7 for a carrier 8. This carrier is tubular in form and is rotatably held within its bearing 7 by means of a collar 9, set-screwed to the carrier, as shown at 10, and ashoulder 11, formed on the carrier. A belt-wheel 12 is secured to said carrier and located on shoulder 11. Adjacent to the front or receiving end or mouth of the carrier, which is flared, as indicated by dotted lines at 13, Fig. 1, the carrier is provided with a tool-rest 14, on which is mounted a suitable turning or cutting tool 15, held thereon by have invented a,

means of a set-screw 16. The cutting edge of said tool 15 isadapted to project through an opening 17 therefor formed in the carrier and leading to the inner passage thereof. In the rear of the tool-holder 14: the carrier is provided with an annular flange 18 and an enlarged portion 19, through which an opening 20 is formed leading to the inner'passage in the carrier. The wall 21, Fig. 4, of opening 20 runs parallel with the axis of the carrier to form a bearing for a slidable member. Pivotally mounted on a stud-pin or screw 22, threaded into the annular flange 18 near its periphery,is a swinging tool-carrying member 23, which is curved around the carrier 8 and formed with a rest or holder 2 L for a cutting or turning tool- 25, adapted to project into the .inner passage of carrier 8 through opening 20.- The tool is removably and adj ustably held within the holder 24 by means of a suitable screw 26. g

A spring 27, having one end thereof bent around a screw 28, carried by flange 18 and bearing againsta fulcrum-pin 29, has its other end hearing against swinging member 23, so as to yieldingly force tool 25 toward the axis-of carrier 8.

Slidably mounted on carrier 8 and longitudinally movable thereon is a limiting or stop member 31, provided with an extended arm 32, having a tapered face 33, adapted to bear against atapered or inclined face 34 of tool-holder 24, so that as the slidable member 31 is moved awayfrom the receiving end of carrier 8 the tool 25 will be forced in toward the axis of carrier 8 by means of spring 27, and as the slidable member 31 is moved :toward the receiving end of carrier 8 the tool 25 will be forced out or away from the axisof carrier 8. w

Slidable member 31 is provided with three annular circumferentially-extending flanges 35, and the mechanism for operating said slidable member consists of a sliding frame 36, provided with an upwardly-extending portion 37, adapted to surround slidable member 31, and between the inner walls of the upwardly-extending portion and the slidable member a bushing or lining 38, of Babbitt or other suitable metal, is interposed.

The frame 36 is provided with a base 39, adapted to slide in a way 40, formed therefor in base 6. Base 6 is provided with an opening 41,'and a lever 42, formed in the nature of a bell-crank and mounted on a suitable stud 43, projects through opening 41 and has a suitable connection 44 to base 39 of the frame 86. The other arm 45 01? bell-crank lever 42 carries a weight 46, movable to different positions thereon and adapted to be held in its adjusted position by .means of a screw 47. This mechanism for operating the slidable member 31 is adapted to force.said slidable member away from the receiving or head end of carrier 8.

On a suitable stud 48 a former or governor in the nature of a cam 49 is mounted and by suitable mechanism (not shown) is adapted to be rotated at a desirable speed. Lever 42 is provided with a bifurcated projecting arm 50, between the furcate parts of which a roller 51 is rotatably mounted. Roller 51 is adapted to bear against the periphery of governor or former 49, and as said governor is rotated lever 42 will be swung so that its movements conform to the path of travel of roller 51, guided by the governor.

It will be seen that in order to get different or varying movements of lever 42 different governors of variable contours may be substituted for the one shown.

It will be understood that the work or material to be operated on, such as sticks, will be inserted into the device at its mouth or re-. ceiving end and will move from the device at the right-hand end. Tool15 is adapted to trim or so form the material or work that it may pass through the device. The tool 20, which is the shaper, will turn the work to conform to the form or outline predetermined by the governor 49.

It will be understood that the particular construction and arrangement of parts as shown may be varied without departing from the spirit of my invention.

Having thus described my invention, what I claim is 1. In a device of the character described, a rotatable carrier provided with a materialpassage therethrough, means for preventing longitudinal movement of said carrier, a cutting-tool mounted on the carrier adjacent to its receiving end, a swinging tool-holder eccentrically mounted on said carrier, a tool supported on said holder and adapted to ex-' tend into the material-passage on the opposite side from the major portion of said tool- 5' 5 holder, a spring for yieldingly forcing said tool toward the center of said passage, a slidable member rotatable with said carrier and provided with a projection adapted to limit the movement of said tool into said passage, means for moving said slidable member iongitudinally of said carrier, and an agent for from the major portion of said frame, means for moving said shaping-tool toward the axis of the material moving through said passage, and means rotatable with and longitudinally movable on said carrier for varying the depth to which said shaping-tool may extend into said passage.

3. In a device of the character described, a rotatably-mounted carrier through which the material-to be operated on is adapted to pass, a turning-tool revoluble with said carrier and mounted thereon adjacent to the receiving end thereof, a swinging frame mounted on said carrier and adapted to extend partially around the material passing through the device, a shaping-tool carried by said frame and adapted to operate on the material on the opposite side from the major portion of said frame whereby as said carrier is rotated said shaping-tool has a tendency to move toward the axis of the material being operated on, means revoluble with said carrier and movable longitudinally thereof for moving said shaping-tool away from the axis of the material, and means for yieldingly forcing said shaping-tool toward the axis of the material. In testimony whereof I affix my signature in presence of two witnesses.
